There are few things in breaking the mule that should be so carefully guarded against as this. For as soon as the animal gets a sore mouth, he cannot eat well, and becomes fretful; then he cannot drink well, and as his mouth keeps splitting up on the sides, he soon gets so that he cannot keep water in it, and every swallow he attempts to take, the water will spirt out of the sides, just above the bit. As soon as the mule finds that he cannot drink without this trouble, he very naturally pushes his nose into the water above where his mouth is split, and drinks until the want of breath forces him to stop, although he has not had sufficient water. The animal, of course, throws up its head, and the stupid teamster, as a general thing, drives the mule away from the water with his thirst about half satisfied. Mules with their mouths split in this way are not fit to be used in the teams, and the sooner they are taken out and cured the better for the army and the Government. I have frequently seen Government trains detained several minutes, block the road, and throw the train into disorder, in order to give a mule with a split mouth time to drink. In making up teams for a train, I invariably leave out all mules whose mouths are not in a sound state, and this I do without regard to the kind or quality of the animal. But the mule's mouth can be saved from the condition I have referred to, if the bit be made in a proper manner. The bit should be one inch and seven-eighths round, and five inches in the draw, or between the rings. It should also have a sweep of one quarter of an inch to the five inches long. I refer now to the bit for the blind bridle. With a bit of this kind it is almost impossible to injure the mule's mouth, unless he is very young, and it cannot be done then if the animal is handled with proper care. There is another matter in regard to harnessing the mule which I deem worthy of notice here. Government teamsters, as a general thing, like to see a mule's head reined tightly up. I confess that, with all my experience, I have never seen the benefit there was to be derived from this. I always found that the mule worked better when allowed to carry his head and neck in a natural position. When not reined up at all, he will do more work, out-pull, and wear out the one that is. At present, nearly all the Government mule-teams are reined up, and worked with a single rein. This is the old Virginia way of driving mules. It used to be said that any negro knew enough to drive mules. I fear the Government has too long acted on that idea. I never heard but one reason given for reining the heads of a mule-team up tight, and that was, that it made the animals look better.
